I am shocked. Shocked. No one would use a widely accessed platform to push a POV nor would it be adequately vetted by professionals for accuracy and completeness and edits limited to trusted sources. Add in that their are many more people who think they are experts that aren't and it is a wonder that Wikipedia's accuracy is above 0%.

No controls. I am going to hazard a bet that if they did this to Web MD, Mayo Clinic or any one of the innumerable other lay accessible web sites, they would get similar results. Given that even the '10 most expensive medical conditions in the country' are not fully explained, categorized or treated having different interpretations or different recommendations is hardly surprising.

Even with professionally sourced and vetted resources you will find differences of opinion. Hell, even the 'reference' documents on a particular condition have differing conclusions depending on whose writing them and who won the argument in the committee.

To a first approximation, everything you know is wrong. Take it from there.

I am a physician, and I admit that I use it on an irregular basis. But let's keep this in context. I don't look up how to diagnose or treat conditions. I do use it to look up obscure things, as well as review anatomy. Information that either is just for personal knowledge that is not critical to management (example: what is the name of the nerve that innervates the serratus anterior?), or information that is hard to get wrong (example: what are the muscles of the knee called? I once had to look up VMO because I could not remember what the "O" stood for). Even then, if it makes even a small difference, I always look it up further in a medical resource. So I am one of the 47-70% of physicians who look up facts in wikipedia. I don't think that is a bad thing.

The situation seems analogous to that of a journalist and/or photographer reporting on a disaster in which people are hurt or killed. It is often said that they would help more if they dropped their notebooks and cameras and pitched in to help rescuers. But then no one would be doing the presumably useful job of recording events.

The researchers in this case were trying to establish the accuracy of Wikipedia articles. Simultaneously editing would be both a distraction and a conflict of interest - much like moderating and contributing to the same Slashdot thread.

in residency, and yes, from time to time I'll look up something on wikipedia on my phone for a quick overview if its a condition I'm not familiar with, or is outside my specialty, and I'm rounding or otherwise away from a computer. However, I don't use it for treatment or diagnostic purposes; there exist much better, peer reviewed sources for that, which I will happily access from a computer. That being said, I'd say a large amount of the wikipedia articles tend to be pretty decent, and at least sound as if they've been written by someone with some sort of formal medical treatment. They get the quick and dirty job done about 75% of the time for me.
